SHIM.

Application filed April 13, 1922.

T aZZ whom it may concern.

Be it known that 1. James H. Benson, a citizen of the United States,residing at Ringsted, in the county of Emmet and State of Iowa, haveinvented certain new and useful Improvements in Shims, of which thefollowing is a specification.

This invention. relates to new and useful improvements in shims fortaking up the ilay between two parts or elements, the primary object ofthe invention being to provide a device of this character which can beeasily inserted into a space to be filled without necessitating theremoval or disturbance of parts causing the space.

Another important object of the invention resides in the provision of ashim for bearwhich is provided with means for detachable engagement withthe bearings for retaining the shim in its proper position.

Another object of the invention is to provide a device of the abovementioned character which is simple in construction, strong, durable andeilicient in operation.

Other objects and advantages of the invention will become apparentduring the course of the following description.

In the accompanying drawings forming a part of the description andwherein like numerals are employed to designate like parts throughoutthe several views,

Figure 1 is a side elevation of the shim illustrating one use thereof,

Figure 2 is a transverse section on line 22 of Fig. 1 illustrating anend elevation of the shim,

Figure 3 is a horizontal transverse sec tion of a bearing showing theshim attached thereto,

Figure elis a section through the shim,

Figure 5 is a perspective view of the same.

In the drawing wherein for the purpose of illustration is shown thepreferred embodiment of the invention, the numeral 6 designates a crankshaft center bearing to which the present invention is adapted to beapplied although it will of course be understood that the invention isnot limited to this specific use as its application as a shim is readilyperceived.

This main center bearing consists of a pair of sections 7i and 8, theformer being supported by a depending bracket 9 as is customary in awell known type of motor vehicle. lower section 8 or a cap of Serial No.555,327.

bearing is provided at opposite sides .n .reof with apertured ears 10throu. i

which bolts i1 pass for sec ring the sections or he bearing around aportion of a crank shaft 12. It is well known that after continued use,the bearing and crank portions of the shaft become worn so that a spacetherebetween is eventually created so that the shaft has end play in thebearing thereby causing detrimental eifects on various parts of theengine of which the crank shaft forms a part. It is also well known thatthis end play of the crank shaft causes poor operation of the magneto asthe magnets are caused to be spaced too far away from the magneto coilsto obtain the intense spark which is essential to the proper functioningof the engine.

In order to overcome these difficulties and to compensate for the wearbetween the bearings and crank shaft without removing the engine fromthe vehicle or removing any of the parts which cause the play therebetween, 1 provide a shim which consists of a semi-circular flat plate13 made of wear resisting material and provide the same with aconveXo-concave inner edge 14 which is tapered or beveled as clearlyseen in Fig. 4: so that the same is substantially wedge shaped.

In order to properly retain the shim in position it is provided with apair of arms 15 which extend outwardly from opposite ends of the shim inopposite directions. These arms are bent as at 16 outwardly from theshim, to extend at substantially right angles thereto. The free ends ofthese arms are provided with apertures by looping the same as at 17. Inthe present instance the arms 15 are provided by a stout piece of wirehaving its intermediate portion attached to the arched portion of theshim plate. This intermediate portion of the wire is arcuated in thesame direction as the inner edge of the shim so as to snugly fit aroundone end of the bearing section 8. The ends of this wire are then bent orlooped in the manner hereinbefore mentioned so that openings are provided for the passage of the bolts 11.

To apply the shim to a bearing, the bolts 11 are preferably removed andthe shim plate is moved so that its beveled edge 14 engages between thebearings and the crank of the shaft so that it can be forced up into thespace caused by wear between the parts.

hen having thus positioned the shim, the loops 17 of the arms thereoiwill be in alinement with the apertured ears of the bearing section 8 sothat tne bolts ll can be properly assembled with the bearings to retainthe two sections the eof in proper engagement, and at the same time theshim will of course be firmly held in proper position to take up theplay between the bearing and the crank shaft. By the particularconstruction of the shim it will be seen that the same can be easilyassembled and associated with the main center bearing of the crank shattwithout necessitating the removal of the engine as is the customarypractice at present when a play between the main center bearing and thecrank shaft is to be remedied.

The foregoing description and accompanying drawings have reference towhat might be considered to be the approved or preferred form of myinvention. I desire it to be understood that it may make changes in theconstruction, combination and arrangement of parts, materials,dimensions, etc. as may prove expedient and "fall within the scope ofthe appended claims.

Having thus fully described my invention what I claim is l. A. bearingshim comprising a hall? washer, a pair of retaining arms extending inopposite directions from the lower convex edge of said halt-washer, saida being bent to extend in diverging relationship in a plane at an angleto the plane of the shim, and the free ends of said arms being bent toform eyelets.

2. The combination with bearing having removable halves, and bolts tosecure the halves togethr, of a shim comprising a halfwasher, a pair ofretaining s extending from the lower arcuate edge or said halitwasher inopposite directions and in a plane parallel to the halt-washer, saidarms adjacent the washer being bent upwardly then in a plane at an angleto the halt-washer, said arms being arranged in diverging relation--ship, and the free ends of said arms being bent to form eyelets to beclamped between the heads of the bolts and the lower hall of thehearing.

In testimony whereof I atiix my ignature in presence of two witnesses.
